Symbol definitions for basic SIS commands

]

}= Carriage return (no line feed, hex 0D) (for URL-encoded commands, use the pipe character,  , instead)

• = Space character

= Pipe (vertical bar) character

*= Asterisk character (which is a command character, not a variable) E = Escape key (hex 1B) (use W instead of Esc for Web browsers)

X!	=	Input number (for tie)	00 = untied
			01	– 08	= the computer video group
			09	– 14	= the low resolution video group
X@	=	Output number	01	– 12 for video
			01	– 06 for audio

NA video input from either of the two groups cannot be tied to an output in the other group. Audio can be tied to any output, regardless of the video group to which it was input.
